Frequency Three Phase Inverter Drives for Water Pumps in Sea Food
Farming

A pumps system controls sea water cycle in a sea food farming
plant. The water from the sea is filtered via several tanks and at
the end to the tank where sea animals live. The pumps become an
important part of this system, water flow is controlled anytime.

A variable-frequency drive (VFD) is a system for controlling the
rotational speed of an alternating current (AC) electric motor by
controlling the frequency of the electrical power supplied to the
motor. A variable frequency drive is a specific type of
adjustable-speed drive. Variable-frequency drives are also known as
adjustable-frequency drives (AFD), variable-speed drives (VSD), AC
drives, microdrives or inverter drives. Since the voltage is varied
along with frequency, these are sometimes also called VVVF
(variable voltage variable frequency) drives.
